As they are now, they consist of 3 equatorial squares, and 2 polar squares. Fine.
But i can see wierd edges here and there, suggesting that you generated this image somehow, or split it somehow, rather than actually creating it from scratch like that (lol).
So i ask, how? How do i transform a normal square texture into a 5-box map like here? Ive been googling, photoshoppin, etc. I cant figure it out. If i could just use a square texture i could, you know expand the polar regions so it looks okay when the ingame sphere-mapping pinches the poles together.
But it seems that only the gasgiants use this mapping method. Why not the other planets? Anyway to change that? Is it the planetmesh itself that has those UV things?
